Small Signal Gain
This block is included only in the PLECS Standalone library.Purpose
Measure loop gain of closed control loop using small-signal analysis
Library
Control / Small Signal Analysis
Description
This block uses the Small Signal Perturbation block and the Small Signal Response block to inject a perturbation into a feedback loop and measure the system response. To see the implementation choose Look under mask from the context menu of the block.
For detailed information regarding small-signal analysis see chapter Analysis Tools.
Parameter
- Compensate for negative feedback
- When set to on, the underlying Small Signal
Response block inverts the reference input in order to compensate for a negative
unity gain that is introduced when the feedback signal is subtracted from a
reference signal.
When set to off, the reference input is taken as is.
